Product Introduction
The Molex 430451214 is a 12-circuit, dual-row header in the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire interconnect in power and signal applications. Typical applications include automotive, general purpose, industrial, medical, and telecommunications equipment.
The 12 circuits in a dual-row layout at 3.00 mm pitch define the board footprint — two rows of six pins each, with 0.118 in (3.00 mm) row spacing.
Construction and Environmental Fit
That covers underhood automotive and sealed industrial cabinet environments.
How It Compares Within the Series
Within the Micro-Fit 3.0 43045 family, the 430451214 (12 positions) sits alongside the 16-position 430451610 at the same 3.00 mm pitch and 8 A per circuit rating. The decision between them is driven purely by the circuit count on your BOM — the footprint, current capacity, and mating half are otherwise identical. Both use the same gold-plated contacts and locking ramp retention.
